简介
Linux/Unix 主机上安装的一个或多个程序包存在漏洞，但供应商表示不会修补此漏洞。描述
Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。- scsihisi_sas删除 debugfs 后将 debugfs_dir 指针设置为空如果 init debugfs 由于内存分配失败导致设备注册期间失败则在 debugfs_dir 不会被设置为空之后会调用 debugfs_remove_recursive()。在设备移除期间将再次调用 debugfs_remove_recursive()。导致访问非法指针。 [ 1665.467244] Hisi_sas_v3_hw 0000:b4:02.0无法初始化 debugfs! ...
